Abstract
The present invention provides a class of hydrochlorofluorocarbons having a tertiary structure, 5 carbon atoms, 1 chlorine atom, 6 to 8 fluorine atoms, and OH rate constants from about 8 to about 15 cm.sup.3 /molecule/sec.times.10.sup.-14. The hydrochlorofluorocarbons are useful as solvents and blowing agents.
